This is an interior photo of Dan Devening's Gallery Devening Projects + Editions with work of artist Volker Saul on the walls. The silhouettes of the people were added via a 3D application to give a sense of scale of the artwork. Show in this screen grab are the controls to scale the "virtual" people to the original photograph.

I included the back white wall so the shadow would wrap up the wall to add realism. This wall was then removed in Photoshop when I composited the computer image with the real photograph.
